Abstract: A driving assistance device includes a travel information acquisition unit, a first information acquisition unit, a second information acquisition unit, a first determination unit, a second determination unit, a first avoidance-amount setting unit, a second avoidance-amount setting unit, and a driving control unit. The second avoidance-amount setting unit sets, when the second avoidance-amount setting unit sets a control amount of a driving control as a second avoidance amount for performing a second avoidance driving action, the control amount smaller than a control amount that is set as a first avoidance amount by the first avoidance-amount setting unit, and sets, when the second avoidance-amount setting unit sets a start timing of the driving control as the second avoidance amount for performing the second avoidance driving action, the start timing later than a start timing that is set as the first avoidance amount by the first avoidance-amount setting unit.

Abstract: A collision avoidance apparatus provided with object recognition means, collision determination means, and notification means. The object recognition means identifies an object around an own vehicle. The collision determination means determines the possibility of a collision between an object identified by the object recognition means and the own vehicle. The notification means notifies the outside of the own vehicle about the movement direction of the vehicle if the collision determination means determines that the target object is an object having the potential for collision with the own vehicle.

Abstract: A control system calculates inputs to a control target that has m inputs and n outputs (m=n, each of m and n is a natural number that is more than one), while designating a plurality of combinations of the inputs and the outputs. A feedback controller calculates, with respect to each designated combination, a control input to a non-interference controller based on a difference between a target value and a current value of the control quantity to make the current value follow the target value. The non-interference controller executes, with respect to each designated combination, a non-interference control to reduce influence due to mutual interference between n control quantities. This reduces the number of combinations of the inputs and the outputs, the combinations whose mutual interference needs considering; thereby, the non-interference control may be easily achieved.

Abstract: In a control apparatus of a rotating device, a voltage command value setting section sets terminal command values on the basis of a command value of a control amount of the rotating device. Individual correcting sections calculate feedback operation amounts on the basis of history information of electric currents flowing in respective terminals of the rotating device and corrects the terminal voltage command values with the feedback operation amounts. A prohibiting section prohibits difference corresponding amounts, which correspond to differences of the feedback operation amounts and an average of the feedback operation amounts, from being reflected in correcting the terminal voltage command values with maintaining polarities when a determining section determines that it is a switching time from one of a power-running control and a regeneration control to the other.

Abstract: A driving support control unit of a driving support apparatus executes driving support control for supporting at least part of driving by a driver. A support determining unit determines whether or not predetermined conditions for terminating the driving support control are satisfied. A physical amount acquiring unit acquires a physical amount corresponding to a curviness degree of a driving lane on which an own vehicle drives. A curviness degree determining unit determines whether or not a curviness degree indicated by the physical amount acquired by the physical amount acquiring unit is smaller than a predetermined degree in the case where the predetermined conditions for terminating the driving support control are satisfied. A termination command unit commands the driving support control unit to terminate the driving support control if the curviness degree determining unit determines that the curviness degree is smaller than the predetermined degree.

Abstract: A control section of a steering controller calculates a steer angle which is a turning angle of a first column shaft based on a first detection value detected by a steer angle sensor, and calculates a second shaft turning angle which is a turning angle of a second column shaft based on a second detection value detected by a second shaft rotation angle sensor. A steering torque detection value is calculated based on a third detection value detected by a torque sensor. An abnormality determination part determines abnormalities of the steering torque detection value based on the steer angle and the second shaft turning angle. Thereby, abnormalities of the steering torque detection value are detected without multiplexing the steering torque detection value. Further, if the steering torque detection value is multiplexed, an abnormal steering torque detection value can be specifically identified.

Abstract: A motor controller has an assist controller that generates an assist instruction AC to generate an assist torque for lightening a steering load based on a detected value of a steering torque, and a follow controller obtaining a target value of a physical quantity regarding a steering operation and generating a follow instruction TC of a follow control. Further, an intervention detector in the motor controller detects an intervention of a driver or of a system, and a restrictor restricts an internal value that is used by the assist controller or by the follow controller, so that a ratio of the assist torque against the automatic steering torque is changed, which makes it possible to switch a control to the driver or to a system without a causing a wrong feeling to the driver.
